5 eral object to provide an improved. construction of wheeled frame for this type ofmachine. I

In the particular construction of machine to which our invention has reference, the picker mechanism which picks or snaps the ears from the standing corn is disposed at one side of the frame, and the husking mechanism which husks or shucks the cars is disposed at the opposite side. of the frame. Each of these mechanisms has a considerable over-j hang at the sides of the machine, with the principal weight of each concentrated at points located outwardly beyond the planes of the two load bearing wheels. As a result of this construction'the weight of each of theaforesaid mechanisms has a lateral fulcrum action about the plane of its adjacent wheel, thereby creating stresses in the frame which tendtobuckle the same upwardly at One of the features of the invention is to provide a frame which is so conamply reenforced against such bending or buckling stresses. Another feature of the invention is to construct this frame so that all tendency of a parallelogram motion between the framemembers is avoided. Another feature is to reenforce the frame against any distorting efiect of the draft forces applied to the frame. I

Referring to the accompanying drawings wherein we have illustrated the preferred embodiment of our invention:

Fig. 2 is a perspective view of the wheeled frame, with which our invention is principally concerned; v V

Fig. 3 is a plan view ofthis frame;

picker mechanism,

ing rolls 1313, which complementary devices,

of. the wheels, showing the arched reenforcing trusses.

Referring to Fig; 1, it will be seen that the which has been designated 8 in its entirety,'eXtends longitudinally of the machine at one side thereof." The husking mechanism, which has been designated 9 in its entirety, is also disposed longitudinally of the machine, at the oppositeside thereof. The details of each of these mechanisms form no part of the invention,

and their general-construction and arrangement is well known. It will, therefore, sufice to say that the picker mechanism comprises the usual gathering members ll-ll, 1 stalks into the machine, and V for guiding the a pair of inclined snapplng rolls 12 12 (Fig.

a which snap or pick the ears from the stalks. The husking mechanism 9 comprises an suitable arrangement of inclined huskstrip the husks, silks, et cetera, from the ears as down along the upper surfaces of the rolls. The picked ears are conveyed from the-picker mechanism 8 to the husking mechanism9 by any well-knowntype of elevator 14:. These machines are usually provided with other such as a wagon elevator 15 for conveying the husked ears up to a point for dumping into a wagon, and a husk conveyor 16 operating beneath the husking rolls for carryingthe husks and refuse back to a point of discharge at the'rear of the machine, all of which is well known. The power for driving the several operating units may be derived from a motor mounted on the picking machme, or from a power take-01f from the tractor, or the traction power of the load bearlng wheels of the picking machine may be utilized to drive these operatlng devices,

such drive forming no part of'the invention. I

The operating parts of the machine are all supported "on a main frame 18 in which are journaled the two-load bearing wheels 19. As shown in Fig. 4:, these two wheels are set inwardly from the sides of the machine, such being desirable for giving the desired clearance for-mounting the picker and the husking mechanisms. As before'rethe latter travel extending bars with their versely entending aXle28 which marked, this arrangement results in both mechanisms having an overhang at the sides of the machine. Referring now to the con struction of the main frame, as best shown in Figs. 2 and 3, it will. be seen that it is of rectangular form and comprises two longitudinally extending angle bars 2122, disposed between the wheels 19, and two transversely extending angle bars 23 and 24- the front and rear ends of theframe. A third cross-bar 25 is provided in back of the rear cross-bar 24. The two longitudinal frame bars 21 and 22 are riveted or bolted to the three cross-bars,,as indicated at 26. Each of these several frame bars is preferably of angle section, and the longitudinally extending bars are disposed with their angles facing upwardly and the transversely an les facing downwardly. The end bar 25 may be provided with additional points of attachment to the bar 24, such by the provision of one or more short connecting bars 27.

The wheel 19 are journaled on a transis disposed substantially centrally between the front and rear crossbars 23 and 24. Bearing brackets 29, which are bolted to the longitudinal frame bars at 31, secure the axle to these bars. The axle is held against rotation, and the wheels 19 have journal mounting on antifriction roller bearigscarried by the axle. Extending inwardly from each of these rollor bearings is a bearing collar 32 which held against rotation by providing the same with one or more notches which receive lugs 33 projecting from the end of the adjacent bearing bracket 29. We have shown the wheels 19 as being provided with sprocket wheels 34, corresponding to a construction whereinthe operating parts of the ma ne are driven by traction power, but any of the other forms of power drive may, of con so, be employed instead of this fraction drive.

Mounted on the outer ends of the a'xle28 are sleeve-like brackets or hubs 35 which are rigidly pinned or keyed to the axle. Extending upwardly from these brackets are webs 36 to which are bolted inverted l .-shaped brackets 37 and 38 for attachment to the picker mechanism and to the husking mechanism respectively, as will be presently described. Projecting laterally from the end of each hub bracket 35 are lugs or ears 3939 for effecting bolting attachment to outer frame bars 41. These frame bars incline inwardly from the bracket hubs and have in Wardly bent ends 42 which are bolted or riveted to the vertical flan 'es of the transverse frame bars 23 and 24. It will be observed that such outer frame bars join the axle to the frame on both sides of each wheel, corresponding to a wheelbarrow mounting of each wheel. The bars 41 resist fore and aft "stresses at the ends of the axle and also carry side boards 52,

. and 24 of the main frame by Lew/3957 stresses tending to rotate the bracket hubs 35 on the axle.

The draft force is applied to the front frame bar 23 at a plurality of spaced points along its length, such points of draft connection being represented by the three pivot eyes 43 which are secured to the bar 23. Two of these pivot eyes arepreferably disposed in alinement with the longitudinal frame bars 21 and 22, and the third pivot eye is preferably mounted adjacent to the picker side of theframe. The draft frame which has pivotal connection with the eyes 43, is indicated at 44 in Fig. 1, such draft frame having mounting on a tongue truck or being adapted for connection directly to a tractor.

Referring to Fig. 4, the picker mechanism 3 comprises any suitable construction of supplementary frame on which the gathering arms and the picker such supplementary frame being repr sented by the two inclined angle. bars 45 and the two horizontal angle bars 46. These angle bars are suitably joined together by other frame bars, one of which is indicated at 47, extending transversely of the horizontal bars '46. The inverted l -shaped bracket 3? which rises from the end of the axle 28, has its upper arm bolted to the bar 47, as indicated at 48. The forward portion of this picker frame is also bolted to the front bar 23 of the main frame, it being noted that the adj acent end of said bar is turned to inclinedownwardly, as indicatedat 49, for fastening to one of the inclined bars 45. of the picker frame may also be connected to the. main frame by. an inclined bar (not shown) extending between the ends of the horizontal bars 46 and the main frame bar 25.

The husking mechanism 9 comprises any suitable frame structure represented by the 53 and the angle plates 54, which are joined by one or more transversely extending bars 55. The inverted L-shaped bracket 38 at this side of the machine is fastened to the frame of the husking mechanism, preferably being bolted to the transverse frame bar 55, as indicated at 56. The front and rear ends of the husking mechanism are also secured to the front and rear bars 23 inclined braces or bars (not shown) which extend diagonally down from the supplementary frame of the husking mechanism to said main frame bars 23 and 24.

It will be observed from the foregoing arrangement that the major portion of the weight of each of the picking and husking mechanisms 8 and 9 is disposed in a vertical plane located outwardly beyond the plane of the adjacent side wheel 19. Thus, this weight in each instance, has a fulcrum action around the lower tread point of the adjacentwheel, tending to create upwardly acting buckling stresses in the intermediate portion of the rolls have mounting,

The rear end.

frame between the wheels. It' will alsobe noted that because of the long forward extension of the gatherer' arms ll and picker rolls 12 beyond the front end of the main frame, which parts engage the corn row, this corner of the frame is subjected to stresses tending to warp the same downwardly. The

through axle 28 serves to reenforce the frame to a limited extent against the buckling stress, but is inadequate to carry all of the stress.

To the end of reenforcing the frame against all of its loads we have provided two arched trusses or reenforcing bars 58 and 59 each of which has connection with the vintermediate point of the axle and with the side portions of the'frame. Secured to the center of the axle is a heavy bearing member 61, from the upper side of which rises adiagonal bracket 62. Extending'from the rear of this bearing at a relatively low point is a second bracket portion 63. The upper truss bar 58 extends diagonally'of the frame andis arched to pass over the upper bracket 62, to which the bar is rigidly bolted at 64. The downwardly inclined rear-send of'the truss bar is riveted or bolted tothe'inner frame bar 21 and to the rear cross bar 24 at the husking side of the'machine as indicated at 26. The'arch of this truss bar continues forwardly for pass- 1 ing overthe upper side'of the other longitudinal frame bar 22, to which the truss bar is rigidly secured through an angle bracket 66, the. truss bar being bolted to such bracket at 67 and the latter being bolted to the longitu- (I dinal frame bar at 68.

The frontend of the truss bar inclines downwardlyandis bolted 'orriveted to thefront frame bar 28 at 69,

adjacent to the corner which carries the forward overhang of the picker mechanism.

. The lower truss bar 59 extends transversely between the inner frame bars 21- 22 and has under the lower bracket extension 63, to which the bar is rigidly'bolted at 71. The upwardly inclined outer ends of the truss bar 59 are fastened to the under sides of the longitudinal frame bars 2122, such as'by the' bolts 31 which secure the bearing brackets 29 in place.-

By virtue of the fact that the arched portions of the two trusses have strut support with the intermediate portion of the axle at points spaced upwardly and downwardly from the horizontal plane of the frame, such trusses form substantial reenforcing means for carrying the buckling stresses set up in the center of the frame, the upper truss 58 acting in tension and the lowertruss in com pression. The forward reach of the diagonal truss to that corner of the frame whichrcarries the forward overhang of the picker mechanism also reenforces this corner against the warping stresses referred t0, the bracket 66 constituting a fulcrum point of reaction for carrying such stresses. noted that-thediagonal truss reenforces the Finally, it should be buckling stresses.
